lie it known that LCLYDE J..MGNERNY,

` a citizen oit the United States, and a resi- 1 dentoi the city of Memphis, in the lcounty furnaces, which will be susceptible of being ot Shelby and-Stateol Tennessee, have invented certain new and useful Improve `ments in Oileurners, of' whichthe follow` ing is a specification. y

rl`his invention relates to hydro-carbon oilburiiers, and oneof the obgects is topro*` Another object oi the invention is to provide means whereby the hydro-carbon, beiiiore it is mixed with the air, may be vaporized into gaseous `or semi-gaseous condition. y y l .t nothcr object ofthe invention is to pro vide a burner adapted for use in stoves and easily assembled and taken apart for `the purpose oit inspection `or repairs. r

lt is also the purpose of my invention to generallyimprove the classot devices to Fig. 5 is a cross-sectional view on the line` 55 of Fig. 1.

Referring now to the drawings by nu-` merals of reference, 1 designates an end casing, here shown as substantially rectangular, and provided with a burner supporting end `wall 2, which carries the burner elements 3 and 4i. Each burner element is substan tially tubular andy provided with longitudi nal partitions 5 and 6, to Jorm upper chainu Specification of Letters Patent.

bers T and lower chambers 8, the lower chambers bein adapted to communicate with the upper chambers through the elongated slots 9 and 10 in said partitions, so that vaporized fuel which enters the lower chambers may find` access to the upper chambers through the slots 9 and 10 in the partitions. and pass out through the ignition slots .l1 formed in the cap or' each 0i? the biirneil elements, as best shown in Figs. l and 2. It will be observed that the upper surface ot each of the burner elements is substantially corrugated to form lips 12 and 13, which bound the ignition slots 11, so that there will be a plurality of wellsdeiined transverse `flames extending throughout each burner element.

The fuel, consisting of the air and gasiied hydro-carbon, is introduced into the burner or burnerelements through thesupply tube 14e, having communication with the endair inlet `chaml'ier in lthe end casing l, throughthe orifice 15 in the wall 2, the oritice 15 alsoserving forthe introduction oi the end of a slip valve 16 which supplies gas to the tube 1et,`and which may be controlled through the medium of a valve stem 17 accessible on the exterior of the cham` ber 1, and adapted to be operated by the knurled button 18.

. 19 and 2O are openings adapted to be controlled by the shutters 21 and 22, whereby varying amounts of air may be admitted to the chamber or casing 1 to mix with the hydro-carbon, the varying proportions being designed to compensate for the varying richness of the gas or vapor. The oil may be fed from any suitable container to the pipe 23 (see Figs. 2, 4 and 5), at a point beneatli the chamber 1. The pipe 23 is divided into two branches 24C and 25, the branch 24 being adapted to be opened and `closed by a valve 26, and said branch is adapted to run the entire length of the burner and enter a vaporizing tube 27, of

`greater diameter than the branch pipe 24,

said vaporizing tube 27 being slightly to one side and above one of the burner elements, as for example, the burner element` 4. The vaporizing tube discharges into the casing ot the valve 16 (see Fig. l). immediately beneath the vaporizing tube 27 is a pilot burner V28, adapted to communicate with the branch 25, and capable of being opened and closed by a. valve 29. The pilot burner is best shown in detail in Fig. 8, as consisting of a tube of relatively small diameter wound-intermediate its ends'i'ii a series of Y and beneatlithetipmay be arranged a` coils 30, and terminating in a burner tip 31 ot' anyV desired construction. The pilot burner may be providedwith a casing 32j, embracing in part the vaporizing tube 27,

trough or oil pan 33, toreceive the'oil dis Charged through the tip 31.

Assuming thatY all the parts are properly i assembled, the operator may rst open the valve 29 and admit a sufiicient quantity of oil to How-,into the pan 33. This may then.

be y ignited, vaporizing the oil flowing through the coils 30,'to provide and vaporize fuel. The flame-f therefrom will act upon the vaporizingtube 27 Yto heat the same, so

that after a sufiicieiit timehas elapsed, the valve 26 may. be operated to admit liquidy fuel throughV the pipe 211 into vaporizing tube 27, the liquid being Vvaporized as it passes through the tubeadjacent to the pilot v and 6, with .their peculiarly formed slots,

will insurea proper'distributionof the mixed gas throughout the upper chambers ofthe burner elements, so thatthe gaseous mixture will burnfreely at the discharge portions of theslots 11 iii aneliicient man.-

I claim:

1. An oil burner comprising a mixing chamber, elongated burners carried thereby, a centrally disposed tube interposed between the burners and communicating with them at one end and with the mixing chamber at the other end, longitudinally disposed partitions in the burners dividing them into upper and lower chambers, the partitions having openings whereby the two chambers may communicate, and means for supplying-fuel to the central tube.

2. An oil burner comprising a mixing chamber, burnei members carried thereby, a tube interposed between said members and communicating with the mixing chamber and with the members, an oil supply pipe, a vaporizing tube into which the pipe dis charges, said vaperizing tube leading inte the mixing chamber, a branch pipe from the oil supply pipe, having a pilot burner to heat the vaporizing pipe and valves in said pipes.

3. An oil burner comprising an end casing having a central opening, a slip valve projecting through said opening, a tube surrounding the projecting end of the slip valve, said tube having terminally located discharge ports, tubular burner members re- Y ceiving the discharged fuel from said ports,

an oil supply pipe having in its line a va ,porizing tube and discharging into the slip `Memphis, Tenn., this 11th day ofv March,
